    Agreeing with above -- "seven by four" would be used when you are talking about the specific dimensions of something and are not interested in total values. Copyright mentions "a two by four" meaning a plank of wood (usually) 2 inchesthick and 4 inches wide.

    I think I read somewhere that two-by-four refers to the unfinished dimensions of the wood -- once it is sanded and smoothed that shaves off the additional half-inch.
